Hello VIshal
I'm not sure what your question is. You seem to have accomplished your objective - or is that just a picture drawn in another tool?
You use Styleset - Composite Text and build up the pieces of the name as shown below:
Result is below:
If you are looking to have each item a different colour as you showed in your example, then use each Attribute individually, then place them beside each other and use the "Lock Position" button in order to make sure that when you move one, the others will move with it.
If your requirements differ from the above then you may consider raising an SR in order to receive more assistance.
Regards,
Pat
